T all whom it may concern:

Be it known that I, R01 R. BEERS, a citizen of the United States,residing at Tulsa, in the county of Tulsa, State of; Okla- 5 homa, haveinvented certain new and useful Improvements in Saw-Filing Machines; andI do hereby declare the' following to be a "full, clear, and exactdescription of them- 'vention, such as will enable others skilled in theart to which it appertains to' make and use the same. i j

.This invention relates to saw filing machines which are particularlyadapted for sharpening carpenters saws.

vThe object of he invention resldes in the provision of a saw' filingmachine WhlCli'GlIlbodies "an improved construction whereby the teeth ofthe saw will be positively maintainedthe same size throughout and in ad-'dition will maintain the bevel of the various teeth the same. f Afurther object of the invention resides in the provision of a machine ofthe char- Iaoter named wherein the file element canjbe adjusted to meetvthe requirements of the particular saw being filed and in which thefile element can be easily elevated 6 out of engagement with the teethof the sawiwhen it is desired to move said element relatively tothesaw.V, 1

With the ab ve andother objects'inview the inventionconsists in thedetails of construction and in the'arrangement' and com- ;bination' ofparts to be"' herei nafter more described and particularly pointed outin the appended claims. p In describing the invention in detailrefiferen'ce will be 'had to the accompanying drawings wherein like"characters. of reference 7 denote corresponding parts in jth'e sevora Vd iI1WhiCh+ ,7 '1 t Figure l 'is a'plan view offla sawifiling machineconstructedin accordancewiththe invention; Fig. '2, a side elevationi'ofsame;
